Lovejoy couplings, being Lovejoy universal Joints or LoveJoy jaw couplings. Both have internal components that has to be maintained, the Lovejoy Universal joint needs its bearings greased and replaced when worn, the Lovejoy Jaw coupling will need to spider insert replaced as it wears.

Twin Spring Coupling offers a one piece design coupling with no internal components that need to be maintained and replaced

Friction Bearing U-Joints compared to Twin Spring Coupling

Friction bearing U-joints replacement

Friction bearing U-joints verses Twin Springs no maintenance power transmission couplings. In the world of universal joints there are only two versions, the old block and pin and the newer needle bearing u joints. Friction bearing u-joints was originally patented in 1904 making it over a century old, and the technology inside it hasnt changed, […]

Jaw Couplings a new high speed no spider flexible alternative

Jaw coupling replacement

Jaw Couplings vs Twin Spring Coupling Jaw coupling is an elastomeric coupling used in a number of different industries, Industrial, distribution, agriculture to power servo motors, pumps or other motors. The Jaw coupling is made up of 3 pieces, a input hub, a insert to absorb shock/vibration (there are 4 types of spider inserts SOX […]

Ruland Uni joints – 2 reasons to buy Twin Spring

Ruland uni joints replacement

Ruland Uni joints Uni joints like all universal joint manufacturers all revolve around the same design, Ruland is no different so all u joints are the same, some of the internal components are different, the hubs can be made stronger but that also increases the price. The universal joint is all the same whether a […]

Lovejoy Uni joints vs Twin Spring Couplings

Lovejoy Uni joints replacements

Lovejoy uni joints The flexible shaft coupling we will discuss today is the universal joint. Originally invented in the 1683 by Robert Hooke the Hooke joint became the universal joint when patented in 1905 by Clarence Spicer. The Spicer joint then with Spicer’s business partner Charles Dana turned into the current day Dana Holdings. Lovejoy […]

Happy holidays and happy new year

Twin Spring Coupling producers of the revolutionary hybrid mechanical power transmission couplings would like to wish you all a happy holiday season and a joyous new year. Here’s hoping that 2021 is a better year for us all. We are going to be making some announcements in early January about a design change for our […]

New TSC Flexible shaft couplings replaces old uni’s and jaws

TSC flexible shaft couplings

TSC Flexible shaft couplings to replace U joints & Jaw couplings The TSC flexible shaft couplings use a set of springs to be able to flex and transfer torque, this makes them more flexible than a standard u-joint  so there is no need for bearings which require the constant greasing a. to make sure the […]

No 1 reason for Coupling failures – bearing contaminants, time for something new?

Coupling Bearing U joint failure

Coupling bearing contaminants – Water, mud, dirt and dust contaminants are one of the many ways that bring uni joints to a halt. Rubber boots, constant greasing and inspections are the usual way used to keep the coupling bearing inside couplings working. That’s part of the ROI but what about the annual cost that adds […]

Coupling Solutions for Industrial power transmission coupling failures

Coupling solutions for industrial sector

Coupling solutions replace Lovejoy Universal Joints, Jaw couplings and other couplings. With the 24/7 demands on industrial couplings especially now with the COVID 19 virus meaning less service people and OEM MRO supplies are available, the service manager of these industrial companies have decisions to make. How do I get the most out of the […]

Couplings – How old power transmission couplings cant last in the era of Industry 4.0 and Amazon

Universal joint replacement

Power transmission couplings – Universal Joints, jaw type couplings, beam couplings, bellows couplings and elastomeric couplings all suffer from the same design flaws. We have always used them, they are the only things we use, we just accept the annual maintenance cost and failure rate. A common story from manufacturers and distributors, the power transmission […]
